There is a lot of user information collected by modern apps, but most of them use general approaches to workouts and recommendations. When trying to understand what is going on with recent trends in fitness mobile app development, I couldn't help but wonder why no apps try to adjust to a user's particular needs and situations.

For example, what if an application changes my workout plan in case I am not able to go to the gym, makes workouts shorter when needed, or modifies training plans according to my current results and progress?

What do you think? Which feature should be incorporated in the existing fitness applications? Do you consider personalization, community, AI coaching, recovery tracking, or anything else more important?

Tell me about it, please, because I want to know your opinion and experience. What feature would motivate you to use such an application for a long time?
